` To all wh/m, t Ina/'y con/cern.-l

Be it known that I, WILLIAM BUNTING, .T r.,

a citizen of the United States, and a resident of Brookline,in the county of Norfolk and State of Massachusetts, have invented certain'n'ewv and usefullmprovements inWater-Closets, of

y is connected to the closet between 'the end of the closet-trap which isnext the sewer and the bowl, thus enabling a soldered joint to be formed between the closet and soil-pipe on the sewer side of the trap and the joint between the metal pipe and the porcelain closetto be made at such a point that all dan` ger of the 'escape of sewer-gas therethrough is avoided. v In view of the fact that thesev` metal pipes above the door-line are unsightly,

4 liable'to corrosion, and also liable to be strained or 4moved so as to impair the tightness of the joints, it has been customary to provide the closet with'a depending apron or pedestal which extends down to thetloor and -more or less vcompletely conceals the' metal trap. Y y y So far as I am aware a metal trap above the floor-linehas been applied only to pedesas washout-closets, an examplevbeing shown in 'my prior patentrNo. 474,985. Owing to the general construction and arrangement of thejwashou't-closet the application of the metal trap thereto'was not difficult; but prior to my invention no successful attempt has been made to provide a I j Siphon 11p-jetl closet 'with a metal dischargepipe which leads from thelbottom of the bowl upwardly and'then downwardly-to the iioorline, in connection with an apron or pedestal which'extends around and completely incloses the discharge-passages ofthe closet.

My invention therefore consistsin 'andu has for its object/the above-described application of a metal trapto a Siphon-jet watercloset.. I accomplish `this object byproviding a vertical face, which extends from the `base of the. closet upward around the discharge-passage of the closet at a point slightly beyond the point where the jet-passage leads is in position toregister withmsaid face'and with apertures thereon whichlead tothe outside of the closet, through which4 boltsv may be passed to clamp the iiangeof the pipe 'to the face of the closet.` y i.

For a more complete understanding of 'my invention, reference is made vtothe 'accompanying drawings, in which-,-

Figure 1 is aside elevation of a closet made according to my invention.Vv Fig. 2 is a'cen tral cross-section thereof on line ojo of Fig. v3. Fig. 3 is a cross-section on line'y y of .Fig.;2.

Fig. 4 is anl enlarged section of I`a fragment of the device, taken on the line z a -of Fig. 3.

Fig. 'is a cross-section onI line ww of Fig. 3. y

In the drawings the bowlfl isprovided with the usual-water-inlet 2, whichk leads to 4tl1e'rim, andtwo jet-passages 3 and 4, whichv lead from opposite sides of the inlet-passage down on opposite sides of the bowl. `A\vent passage 6 is formed in the bowl directly below the inlet-passageand centrally ofthe 'bowl. :An apron 8` extends downwardly on all sides of the bowl and extends rearwardly,

so that a chamber 9 4is formedbetween the apron andthe portion of the kcloset in which 'the inlet and vent passages are formed.-

The front wall of chamber 9 consists' of a` I liat vertical 'face `10, v-which extendsupward'` from the'base 'oriioor line ofthe closet, the

` Y plane of this face intersecting the. dischargepassage of thev closet 'a short distance -in the rear ofthe point where the jet-passage entersl 'v i it. A laterally-extending wall 11 is formed on each Vside of the closet, therearfside lof each of whichis in the same plane as that of i '9U face l0 and forms a lcontinuous surface there-l with. Said Wallsextend laterally a sufficient Y distance to form awide face on each side of thedischarge-pa'ssage of the closet. `(See Figs. 3 land A portionlo'f-thisface 'abouty the passage is preferably recessed (see Fig. 4)

in order to receive a sheet of `r'ubbei` packingl r A metal Siphon-pipe 13 is-y arranged in said chamber 9 .andissoldered or, otherwise connectedto themetal soil-pipe 14 at thei'loor-l line.A The intake'end of thel siphonhasametal flange l5 securely lsoldered thereto in a vertical position, and the front side of said 'plate is provided with four sym metrically-arranged screw-threaded bosses 16, into which four correspondingly-threaded bolts 17 are screwed, said bolts passing through corresponding apertures in the walls 11 and in packing 12. The apertures in the packing are enlarged, so that the bosses 16 set into it, as shown in Fig. 4. In practice the heads of bolts 17 are covered by porcelain caps 18, so that no metal whatever is visible from the outside. All earthenware parts of the closet are formed in one piece, so that the whole outside surface of the closet and pedestal presents a finished and unbroken appearance.

In setting up the closet the siphon 13 is first soldered or otherwise tightly connected to the soil-pipe 14, and as this pipe (being concealed) is preferably made of lead it may be easily bent, so that the screw-threaded bosses on the plate 15 will exactly register with the bolt-holes through the walls 11 of the closet, this plate having been previously soldered to the intake end of the siphon. The packing 12 is then placed against the face of the plate 15, sothat the bosses 16 thereon set into the packing and support the same. The closet is then lowered down over the fixed Siphon-pipe until it rests on the floor and is then moved rearwardly, so that the packing 12 enters the recess formed about the discharge-passage in the face 10 of the closet. The bolts 17 are then screwed into bosses 16 from the outside of the closet, clamping the packing firmly between the face 10 and the plate 15. It will be noted that the joint thus formed will be below Ithe water seal in the closet, so that it will be impossible for any sewer-gas to escape therethrough in case the joint should not be tight. lf, however, the joint should not be tight, it would immediately disclose the fact by leaking water. As a matter of fact if the joint is made tight in the beginning it will remain so practically indefinitely or for a long term of years, provided the joint is not in any way molested. As the `joint and the Siphon-pipe are completely inclosed, this latter possibility is very remote.

With the above-described construction I amV enabled to provide a Siphon-jet watercloset with a metal Siphon-pipe in such a manner that the metal pipe is completely concealed and the closet presents a finished appearance. I moreover produce a construction in which the connections between the closet and metal pipe may be conveniently and effectively made in such a manner as to in no way impair the appearance and usefulness of the closet. The fact that by this construction I am also enabled to form all the earthenware parts of the closet in one integral piece and to avoid the necessity of making the apron portion in two sections is afeature of great importance, for the flanges and bolts necessary to connect two such sections would be unsightly. Moreover, it is practically impossible to fit two porcelain parts together in a manner which is at all satisfactory, for the reason that the parts become distorted in fir ing and will leave open joints when they are connected.

Having described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is as follows:

1. A water-closet of the character described, comprising a bowl having a discharge-passage which leads rearwardly from the bottom thereof, said bowl being provided with a substan tially vertical face on its rear side which completely surrounds the end of said passage, laterally-extending walls on each side of the bowl, the rear surfaces of which are continuous with said face, rearwardly extending walls which extend from said laterally-extending walls beyond said face and from the rear side of the bowl above said face to the floor-line and which unite into a continuous wall to form a chamber which is completely closed except at the bottom, said laterallyextending walls being provided with apertures which pass through to said chamber from the outside,all of said parts being formed of one integral piece of earthenware, for the purpose set forth.
